 Additional Information 



Rubber Adhesive Offers High Tack with Excellent Chemical Resistance
The durable backing of 3M™ Photo Film Splicing Tape 8421 is ideal for splicing most film for web and photo processing. The white backing is identifiable in splicing applications. In addition, the polyester provides additional abrasion protection for sealing, edging and color-coding. The rubber adhesive sticks well to a variety of films, offers excellent chemical and solvent resistance, and features high shear strength. The tape remains flexible at -60ºF (-50ºC) and is dimensionally stable up to 300ºF (150ºC).
